I I .My invention relates to an adding-"machine -;and"1nore particularlyto that class ofaddingmachincs known as the Standard Adding ".Machineand as shown and described in the patcnt to W. W. Hopkins, No. 683,939,of 'L' October 8, 1901.

p ()ne of the principal objects of my inven- Ltion is so .to constructthe adding-machine above referred to that the direction of rotation ofthe type-wheels is not reversed when taking the total. This constructionenables QIDQ to use but asingle set of type upon each iftypc-wheel inplace of two sets, as in the Hop kins machine. 1 Other advantages arealso obtained. from this construction, as it enables many operaf tionsto vbe performed by the machine which could not bedone or could only bedone with great di'lliculty in a machine inwhich the'direction of thetype-wheels is reversed upon 7 taking the total. l ()ne oi theadvantages attendant upon the above construction is that the machine canbe provided with an error-key mechanism,

fore it has been placed in theaccumulating "mechanism. or arding-wheels, thus avoiding any disturbance of the add ng-wheels when machine. It also places the entire work of transferring the number to theaccumulating I. incchl n risni, as well as the carrying on the "hand e,thus relieving the order-keys of considerable work, and consequentlylightening their touch corrcspondingly. Another advantage obtained fromthis con- I strnciion is tl'iat; the machine can beprothe total-lever.

Byinen-ns of this construction the upperend ol the dog 100 can be thrown into engagenient with tire gear 101,carrying the type-wheels 102, so as to move in the same direction inwhich the motion is imparted to said gears 101, thus insuring thetripping of the pewls 9e innnediotcly alter the gear 101 5 be begun itsrotation.

The intermediate gears are successively engaged by alongitudinally-sliding gear 105, mounted upon a shaft 106. The gear 105is so mounted upon the shaft 106 to slide longitudinally thereof but tobe in capable of independent rotation. The longitudinal movement of theyear 105 is controlled by a bent arm 10?, carried by the carriage 74 andengaging with a groove in a, sleeve 10b, nttn-cl'ied to said Wheel 1115.The l'lilleiinfllllti gear 95 is loosely mounted upon a shaft 109,carrying a comb 11(1, and encl'i of said intcrn'iediatc gears isprovided with a pin .1 1 Ledopted to engage with the said comb 110 andwith a stop 112.

The lugs 120 are also adapted to engage with .124, secured between theside rames 66 and 67. Each of the tripping-pawls 122 rests upon a pin125 in a retaming-lpawl 126, which.

holds the carrying-bar to the ft in its normal position. Each of thebars 123 is provided witha downward projection 127, which normally restsagainst a plate 128, carried in a A The object of this plate 128 is toreturn the carrying-bars to their normal position after any bar has beentripped in the operation of adding. In the Hop uns patent above referredto the plate 128 is normally but of engagement with the downward pro--ject1on 1.27, so that the carrying-bars 123 might possibly be trippedwhile the parts are in normal position. In my construction, however, thebars 123 are securely locked in their normal position until the propertime in the operatio'nof the machine when the bars 7 should be trippedto carry. The shaft 110 is carried in a frame/ 130, mounted on a rock-Shaft 131, said shaft being journaled into side frames 66 and 67.

The operation the parts above described is, briefly, as follows: Inwriting inv a number one ofthe order-keys 70 is first depressed torelease the carriage 74 and position the same in the correspondingorder, so

. that the wheel. 105 willmesh with thc'intermediate Wheel of the ordercorresponding to the left-hand digit of the number tobe written. Thenumeral-keys 76 are then depressed so as to actuate the wheel from themotor 91 and at the same time feed the the intermediate wheels 114 arerotated by mechanism hereinafter to be described, as diagrammaticallyillustrated in Fig. 40, so as to return the intermediatewheels 95 and .tpe-Wheels 102 to their normal position,

tius removing the number without in any Way affecting the adding-wheels118. if, however, the proper munber placed in the machine, the handle isoperated so as to throw the adding-wheels 118 into engagement with theidle wheels 1 14, and the intermediate wheels 05 are returned to theirnor mal posltlon by the rotation of the shaft 100 and the consequentengagement of its comb with the pins 111 on said wheels, so that thenuinher is transferred from the (y )cwheels 102 to the adding-wheclsl18,as dingrammatically illustrated in Fig. 41. in taking the sum'theaddingwheels 118 are "thrown into engagement with the idle wheels 1.14and the shaft 119 rotated so as to bring the comb 121 into engagementwith the lugs on said adding-wheels, so that the sum is transferred fromsaid adding-wheels to the type-wheels carried by the gears 10]., asdiarammatically illustrated in Fig. 42. t will be evident that owing tothis construction the type-wheels 102 are rotated in the same directionwhen taking the sum' and when writing a number into the machine. At thesametimc that the sum is transferred from the adding-wheels 118 to thetypc-wheels 102 the tripping-pawls 100 of the order stoppawls 96 arethrown into engagement with the gears 101 of the t ype-wheels 102, so asto properly position the carriage 74. When the type-wheels 102 arereturned to-Zero, after ta ting the sum in the ordinary operation of themachine, the adding-wheels 118 are moved out of engagement with the idlewheels'114, as shown in Fig. 43, so thatyvhen the type-wheels arereturned to zero the adding-Wheels will also remain at zero. If,however, it is desired to take a snbtotal that is, H

to print the total in the machine and again return it to the addingmechanism, so as to have other numbers added therctothe suhtotal-key,hereinafter'to be described, is operated so that the. adding-wheels 118will remain in engagement with the idle wheels 11 1 and the sum. will beretransferrml to the adding-wheels in the same manner that a numher istransferred from the type-wheels to the adding-wheels in the ordinaryoperation of the machine.

The frame 130, Figs. 2 and 17 to 22', is held in its normal position, soas to hold the add-. ing-wheels 118 out of mesh with the intermediatewheels 114 by means of a coiled spring 132, attached at one end to thesaid frame and at the other to the side frame 66. In order to force theframe down and bring the adding-dipole into engagement with the idlewheels 114, I provide on the inner face of the side frame 66 a cam 133.(See also Fig. 4.) The rock-shaft 120 is operated from the handle andcarries an arm 135. The arm 1-35has pivoted to it an arm 136, carrying'apin 137, which projects through the said arm at both sides, onev endcoopm'ating with the cam 133 and-tho other bearing upon the upper edgeof the frame 130. In the ordinnr operation ol'the machine when thehandle is operated toroclt thc'shaft 120 the pin 137 is moved to tl iontbetween the cam 133 and the frame 130,,as shown in Fig. 19, thus forcingthe framcdown and bringing the addingwhcels into mesh. with the idlewheels 114. Upon reaching thoforward end of its troke, however, the pin137 passes below 'tlieguidew 138, carried on a pivoted arm 130, and onits rearward movement is guided by the inclined surface of the guide138, so as to was above the cam 133. The adding-\\'hcofs are now wheelsas far as the cam mechanism is conund in detail in Fig. 23.

corned. In order to insure the proper operation of the parts,howe'ven-it is necessary to hold the said wheels in mesh during aportion of its back stroke. fi o accomplish this, I provide the framewith a pin or rojection 14:7 and the arm with a siini ar pin orprojection 1413. The pin 1 18 passes over the :pin 147, and this holdsthe frame 130 in its depressed position until the'arin 135 has receded asufficient distance to disengage the pins 147 and 1 18. In taking thetotal, however, it is necessary to kee the addingwheels out'of mesh''ith the id e wheels while the handle is being operated. This isaccomplished by the mechanism shown in Fig. 9 The pin 137 rests upon apin 134, which projects through an opening in the side frame 96. Thispin 138 is carried by a lever 140, pivoted at 141. The lever is providedwith'two notches 142, which engage with a dog 143, which is adapted tohold the lever ineither of two positions.

In the normal position of the lever, as shown in Fig. 8,'-the pin 137 isfree to move below the cam 133, but when. the lever is thrown into theposition shown in Figs. 9 and 23 the pin will pass above the cam 133. The lover is thrown in its second position when the total-key is operatedby a mechanism which will be hereinafter described. The lever isreturned to its normal position either when the handle is pulled or whenit is desired to take a subtotal.

in order to return the lever upon a pull of the handle, the shaft 129 isprovided with an arm 14%, adapted to strike a rear extension of thelever 1 10 and return to its normalposition.

in order to return the lever to its normal position to take a subtotal,the case 61 is provided with a subtotal-key 146, Figs. 1 and 9, which isadapted to bear upon the forward end of the said lever 140.

in the ordinary operation. of the machine when the shaft 129 is rockedby the pull of the main handle the pin 137 passes below the cam 133, soas to swing the frame 130 on its pivot 131, and thus move the addingwheels into mesh with the idle wheels, so that the number may betransferred from the typewheels to the adding-Wheels. Upon the returnmovement, however, the pin 137 passes over the top of the can'i 133, asillustrated in- Fig. 22, so as to allow the adding-wheels to move out ofengagement with the idle wheels. The pin 148 on the lever 135, however,remains in engagement with the pin 147 on the frame 130 a suilicientlength of time to hold the idle wheels and adding-wheels together longenough to insure the proper carrying of the addingovheels. When thetotalis taken, however, the lever is operated by mechanism hereinafter to bedescribed, so that it is best shown in Figs. 3, 1, 10, and 11.

is moved into. the position shown in Fig. and immediately its pin 13 i Sl1ils.GS. against the pin 137 and raises it, so that upon the forwardmovement of the link 136 it Jasses above the cam 133', and consequent ytoe adding-wheels remain out of mesh with the idle Wheels, as has beenhereinbefore described, and the adding-wheels remain at zero after thetaking of the sum. When a subtotal is taken, however, the lever 1. 10 isreturned to its normal position, so that the adding-wheels are throwninto mesh with the idle Wheels, and the sum is retransferred from theprinting-wheels to the eddin -wheels.

The mechanism. operated by the error lirfy 1c error-key 150 is carriedby a key bar 151 pivoted to .the frame :67 at 152. The key-- bar 151 isprovided intermediate of its length with a slot 153, which engages witha pin 154;, carried on a segmental rack 155, loosely mounted on the endof the shaft 129. This rack 155 engages with a pinion 156, rigidlysecured to the end of the idle-wheel shaft 115, so that when theerror-lrey isdepressed the wheels 95, 101, and 114 will be rotated inthe direction diagrammatically illustrated in Fig.

idly secured to'one end of-a sleeve 161, (see also Fig. 5,) mounted upona shaft 162. the oppositeend of the sleeve 161 is an arm 163, connectedby a link 16 1 with an arm 165, loosely mounted on the handle-shaft 72.The arm 165 is provided with a pin 17 2, engaging a cam 173, alsoloosely mounted on the shaft 72. This earn 173 returnsthe carriage toits normal position. A pin-and-slot connection 174 connects the shaft 72and the earn 173, so that the said cam-can be moped independently by theerror-key and the handle. The arm 163 is also provided with a projection166, which isconnected by slotted link 157 with an arm 168, rigidlysecured to one end of a rocleshaft 169. This rockshaft 169 carries ablade 170, adapted to release the printing slide 171, which will. behereinafter more fully described. The operation of the error-key thusreturns the printing, intermediate, and idle wheels to their normalosition and also returns the carriage and t 16 printing-slide to theirnormal position. In operating the error-key it is also necessary toprevent the feeding of the paper. The mechanism by which this isaccomplished is shown in detail in Figs. 25, .25, and 27. 17 5 is thepaper-feed pawl, which engages with ratchet-Wheel 176, on the end. ofthe paper-roller 177. The said pawl 17 6 is pivoted to a toothed segment178, (see also 157 is a segmental rack which is en- -Figs.' and 29,)carried bgwthe si ideiframe es wit a second 67; This segment 178 messegment 179, which is rigidly secured to the shaft 129 and is there oreoperated each timethe handle is pulled forward, thus accomplishing thefeeaing of the paper in the 1 operation-of the machine. In oroer toprevent the feeding of. the paper when the error- -.key is operated,Ipivot to the side frame 67 a lever 180, provided with a pin-181,' projecting beneath the forward end of pawl 175.

This lever 180 has a rearwardly-projecting tailpiece 182, which isarranged in the path of the pin 154, which is moved by the error-key.Thus when the error-key is operated the lever 180 is moved into theposition shown in Fig, 26, raising the pawl 175'out of en agement withthe ratchet-wheel 1-76. The ever tion 186.

is'rocked into the position shdwn in Fig. 27. T Upon the return of theshaft to its normal g position th'e'tooth186 engages with a shoul,

(ier on the arm 185 and throws the same to the rear, thus returninthe-lever 180 to its normalposition. As t e arm 185 nears the end of itsmovement a rounded should er 187 on the undereCge of the same engageswith the pin 189 and moves the said arm 185 slidmgly upwari so as tobring it out of engagement with the tooth 186, so that it can again bethrown forward by the movement of the error-key. The movement of thepaper feed pawl 175 can be varied by an eccentric 1.90,, earned by thesegment 178 and held in position bya thumb-screw 191.

When a number is erroneously placed in the machine, the error-key 150is. depressed,

thus swinging the error-key bar151 on its The first movement of theerrorkey .bar 151 is communicated, through the pin 154, working in theslot 153 in said bar, to the toothed sector 1'55, mounted on the shaft129. This sector being in engagement with the wheel 156, secured to theend of the shaft 115, upon which are mounted the idle wheels 11 1, thesaid shaft rotated, so as to bring its cam 116 intoengagement'with thepins 117 on said idle-wheels, thus rotating the idle wheels andreturning the/intermediatc, wheels 95 and type-wheels 102 to zero.

% V the sleeve 161 onthe shaft'162.

The movement of the key-bar 151 is-also communicated, through the link159, to the arm 1.60, (see. Fig. 1.0, which is secured to I The movementof the sleeve 161 is coimnunicated, hrough the arm 163 and link 164, tothe earn. 1 73, which returns the carriage 74 to its normal position;The movement is also comarm 63 through the link 167 and arm 168 to therock-shaft 169, carrying the plate 170, which releases theprinting-slide 171 and allows the same .to return to its normal posi-'180, and therefore the pin 181 of this lever raises the feed-pawl 1-75out of engagement 'municated from the projection 166 on the with thefeed-wheel 176, as shown in Fig. 26

of the drawings, so that when the handle is operated the paper-feedmechanism will not be actuated. Upon the return of the handle, however,the tooth 186 on the shaft 129 engages with the shoulder on the link1'87 and draws said link to the rear, so as to return the lever to itsnormal position and allow the feed-pawl 175 to return into engagementwith the feed-wheel 176.

In order to lock the order and numeral keys' when the error-key isdepressed, the

the error-key, as hereinbefore described, is provided with steam-plate195, Figs, 5, 31,

and 32, having a' eam surface 196, which bears upon a pm 197, carried ona rocking bar 198. (See also Fig. 24.) This bar 198 is pivoted to theside frame 6-8 by means of a pin 199, as shown in Fig. 24. The upperend'of the rocking arm 198 is provided with an inclinedaportion 200, soas to be operated 9 rock-shaft 169, which is operated through by thetotal-key, as will be hereinafter described. The lower end of saidbarbears against an arm 201, which is adapted to move acomb 202, Figs.land 2, and thus lock the order and numeral keys against depressionafter the error key has been depressed. the pull of the handle, the saidcam-plate is provided. with a pin 203, which passes through a slot 204in an arm 205.

v This inclined portion 263 is adapted to oper ate on a lock-plate 264,pivotedto the, plate 262' at 265." This plate 264 has a lockingprojection 266, which is adapted to project below the total-hey 211 whenthe arml261 is '1 moved forward. The plate2'64 is'held in its normalposition by means. of a coll-sprang 267. The arm 260," which operatesthe shaft 129, hasattached to it a link 270, the oppo- 201.,'hereinbcfore described, and also has at a The link 272 has in itsupperend a pin 273, passing through a slot'274 in a plate 275. The object ofthe 5 handle-shaft 72.

plate 27 5 is to operate the i'nechanism for re- ,turnine the printng-wheels to ,zero upon the operation of the handle.

The lower end of the plate 27 5 is bifurcated and straddles the Theupper end of the plate 275 is provided with two cam-slots 276 and 277.The slot 277 is L-shaped, as best lof the shaft 115, In addition to thecut he first movement of the total-key bar moves the comb 121longitu'di-.

so that no movement will be imparted to the plate 275 during the firstpart of'the movemerit of the handle. This enables the print-.

ingv and certain other operations to be per formed before the shaft 109is rotated to return tie intermediate. and type wheels to zero. As soonas the pin 273 has reached the lower end of the slot 274 the plate 275'will be drawn downward, thismovement bein al-' lowed byqthe bifurcatedend of said p ate.

the plate 275, thus rotatingthe shaft 109.

Durmgfthe time that movement is imparted to the sector 27 9' the stud278 will be in the vertical portion of the slot 277. As soon as the endof the vertical portion is reached the plate 275 will move forwardinstead of downward, and the sector 279 will remain stationary. Duringthe downwardl 'mo'vement.off

the plate 275 the transfer of the number from the printing-wheels to theadding-wheels iscompleted, so that the remainder of the hair die-strokeconsists of what Iterm safety" rod and has no effect on the transfer ofthe num her, but only insures the completion of the other movements ofthe machine, such-as carrying. In addition to the arm 271 thehaiidle-shaft 72- has secured outside of the side frame 68'an arm283,.to which is ivoted a link 2284., attached to the piston-rot 285 ofa dash-pot'286. The object of-the dash-pot is to insurethe even. andsteady return of the handle and parts operated thereby.

The shaft 109 has secured to it a. projection or'tooths290, Figs. 6, 17,and 18, which is adapted to strike against the arm 291, and thus releasea lockingmechanism now to' be described. Secured to the end ofthe idlewheel shaft immediately. inside of the side frame 64 is a disk 292.(Shown in Figs. 6 17, and 18.) This disk has a cut away portion 293,adapted to-receive a down ward projection 294 hpon the adding-wheelframe 130, so that when the disk is in its-nor mal position as shown inthe figures referred to, the adding-wheel frame'can be de ressed. When,however, the shaft 115, an consequently the disk 292, is rotated,-1tw1llbe 1mpossible to depress the adding-wheel frame.

This disk thus acts as a lock forthe total-kc during the time that theerror-key is depressed, as the error-key causes the rotation
